Abstract

The present paper provides a brief introduction to a holistic approach to ship design optimization, defines the generic ship design optimization problem, and demonstrates its solution by using advanced optimization techniques for the computer-aided generation, exploration, and selection of optimal designs. It discusses proposed methods on the basis of some typical ship design optimization problems of cargo and naval ships related to multiple objectives, leading to improved and partly innovative design features with respect to ships’ economy, cargo carrying capacity, safety, survivability, comfort, required powering, environmental protection, or combat strength, as applicable.

Highlights

Summary

Introduction

Ships are built to cover needs of society through the provision of specific services. Coupled with the design process is design optimization, namely the selection of the best solution out of many feasible ones on the basis of a criterion, or rather a set of criteria Such evaluation criteria are the shipbuilding cost or the required freight rate for merchant ships or more complex ones that include, besides economy, ship performance in terms of safety, comfort, survivability in intact and damage condition and environmental friendliness. The INSC is based on a similar philosophy like the Goal Based Standards (GBS), currently discussed for merchant ships at the International Maritime Organization (IMO). It addresses, specific naval ship features and methods of operation. The code offers an off-the-self safety and performance management system for navies that need to establish a system of self regulation
